摘要

摘要目的：患者信息的加密已成为医疗超声仪器中的一个重要问题，以确保在非现场访问图像时信息的安全。该算法用于对私人医学图像进行加密并传输加密后的图像，以提高加密能力和经过的时间。材料和方法：在改进的Rivest-Shamir Adelman（RSA）算法中，我们使用三个素数生成公钥，其中包括一个固定的Mersenne素数，以比较加密能力。我们使用改进的RSA算法和医学超声成像仪器中的乳房模型计算并比较了经过的时间。结果：由于使用三个素数所用的时间更长（1.2337 s）比使用两个素数（1.0712 s）。然而，使用固定梅森素数（0.8360 s）类似于使用两个素数（0.8389 s）。结论：与使用两个不是梅森素数的素数的算法相比，我们提出的加密算法在医学超声成像中提供了改进的加密，同时传输图像具有足够的经过时间。

Development of modified RSA algorithm using fixed mersenne prime numbers for medical ultrasound imaging instrumentation

Abstract Purpose: Encryption of patient information has become an important issue in medical ultrasound instrumentation to secure information when images are accessed off-site. The proposed algorithm is used to encrypt private medical images and transfer the encrypted images to improve the encryption capability and elapsed time. Materials and methods: We generate a public key using three prime numbers, including a fixed Mersenne prime number, in the modified Rivest-Shamir-Adelman (RSA) algorithm to compare the encryption capability. We calculated and compared the elapsed time using the modified RSA algorithm with a breast phantom in the medical ultrasound imaging instrumentation. Results: The encryption capability is improved because the elapsed time when using three prime numbers is longer (1.2337 s) than that when using two prime numbers (1.0712 s). However, the elapsed time using fixed Mersenne prime numbers (0.8360 s) is a similar to that using two prime numbers (0.8389 s). Conclusions: Our proposed cryptographic algorithm provides improved encryption in medical ultrasound imaging compared to algorithms that use two prime numbers that are not Mersenne prime numbers, while transmitting images with adequate elapsed times.

期刊介绍： omputer Assisted Surgery aims to improve patient care by advancing the utilization of computers during treatment; to evaluate the benefits and risks associated with the integration of advanced digital technologies into surgical practice; to disseminate clinical and basic research relevant to stereotactic surgery, minimal access surgery, endoscopy, and surgical robotics; to encourage interdisciplinary collaboration between engineers and physicians in developing new concepts and applications; to educate clinicians about the principles and techniques of computer assisted surgery and therapeutics; and to serve the international scientific community as a medium for the transfer of new information relating to theory, research, and practice in biomedical imaging and the surgical specialties. The scope of Computer Assisted Surgery encompasses all fields within surgery, as well as biomedical imaging and instrumentation, and digital technology employed as an adjunct to imaging in diagnosis, therapeutics, and surgery. Topics featured include frameless as well as conventional stereotactic procedures, surgery guided by intraoperative ultrasound or magnetic resonance imaging, image guided focused irradiation, robotic surgery, and any therapeutic interventions performed with the use of digital imaging technology.
